/**
 * The following expressions are available to use in most parameters:
 *
 * ## Variables
 *
 * - `$F`: current frame
 * - `$T`: current time
 * - `$OS`: current node name
 * - `$CH`: current param name
 * - `$CEX`: input centroid x component
 * - `$CEY`: input centroid y component
 * - `$CEZ`: input centroid z component
 *
 * Those variables are aliases to the javascript math module:
 *
 * - `$E`
 * - `$LN2`
 * - `$LN10`
 * - `$LOG10E`
 * - `$LOG2E`
 * - `$PI`
 * - `$SQRT1_2`
 * - `$SQRT2`
 *
 * In some parameters which can evaluate per entity (which means per point or per object),
 * it is also possible to use variables to access attributes:
 *
 * - `@ptnum` will evaluate to the current point index
 * - `@vtxnum` will evaluate to the current vertex index
 * - `@primnum` will evaluate to the current primitive index
 * - `@objnum` will evaluate to the current object index
 * - And you can also refer to any existing attribute, **using @ following by the attribute name**.
 *
 * For instance:
 *
 * - `@P.x` evaluates to the **x** component of the position.
 * - `@P.y` evaluates to the **y** component of the position.
 * - `@P.z` evaluates to the **z** component of the position.
 * - `@N.x` evaluates to the **x** component of the normal.
 * - `@N.y` evaluates to the **y** component of the normal.
 * - `@N.z` evaluates to the **z** component of the normal.
 * - `@Cd.x` evaluates to the **x** component of the color.
 * - `@Cd.y` evaluates to the **y** component of the color.
 * - `@Cd.z` evaluates to the **z** component of the color.
 * - `@uv.x` evaluates to the **x** component of the uv.
 * - `@uv.y` evaluates to the **y** component of the uv.
 *
 * Using the attribCreate, point or normal SOPs, you can mix and match them.
 * For instance, if in the point SOP, you set to the x component `@uv.x` and y component `@uv.y`
 * then the points will be transformed to look like in UV space.
 *
 * Another common setup is to use an attribute create to add an attribute `id`, with `@ptnum`.
 * This way, every point will have a unique id.
 * You can then use this id in the following nodes, or even in a material.
 *
 * Instead of having an attribute id that goes from 0 to the number of points in your geometry,
 * you can also create one that goes from 0 to 1, using `@ptnum / (pointsCount(0)-1)`
 *
 *
 * ## Math expressions
 *
 * The following are native javascript functions:
 *
 * - abs
 * - acos
 * - acosh
 * - asin
 * - asinh
 * - atan
 * - atan2
 * - atanh
 * - ceil
 * - cos
 * - cosh
 * - exp
 * - expm1
 * - floor
 * - log
 * - log1p
 * - log2
 * - log10
 * - max
 * - min
 * - pow
 * - random (which aliases to Math.rand())
 * - round
 * - sign
 * - sin
 * - sinh
 * - sqrt
 * - tan
 * - tanh
 *
 * If you are targetting ES6 (available in modern browsers), you can also have:
 *
 * - cbrt
 * - hypot
 * - log10
 * - trunc
 *
 * The following are aliases from the [Polygonjs CoreMath](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/math/_Module.ts) module:
 *
 * - clamp
 * - degToRad
 * - fit
 * - fit01
 * - fitClamp
 * - fract
 * - mix
 * - radToDeg
 * - rand
 *
 * And the following are alias to the [Polygonjs Easing](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/math/Easing.ts) module:
 *
 * - `easeI2( number )`, is a shortcut for `ease_i( number, 2 )`
 * - `easeO2( number )`, is a shortcut for `ease_o( number, 2 )`
 * - `easeIO2( number )`, is a shortcut for `ease_io( number, 2 )`
 * - `easeI3( number )`, is a shortcut for `ease_i( number, 3 )`
 * - `easeO3( number )`, is a shortcut for `ease_o( number, 3 )`
 * - `easeIO3( number )`, is a shortcut for `ease_io( number, 3 )`
 * - `easeI4( number )`, is a shortcut for `ease_i( number, 4 )`
 * - `easeO4( number )`, is a shortcut for `ease_o( number, 4 )`
 * - `easeIO4( number )`, is a shortcut for `ease_io( number, 4 )`
 * - `easeSinI( number )`
 * - `easeSinO( number )`
 * - `easeSinIO( number )`
 * - `easeElasticI( number )`
 * - `easeElasticO( number )`
 * - `easeElasticIO( number )`
 *
 *
 * ## String expressions:
 *
 * - precision (alias to the [CoreString](https://github.com/polygonjs/polygonjs-engine/blob/master/src/core/String.ts) module precision method)
 * - [strCharsCount](/docs/expressions/strCharsCount)
 * - [strConcat](/docs/expressions/strConcat)
 * - [strIndex](/docs/expressions/strIndex)
 * - [strSub](/docs/expressions/strSub)
 *
