/**
* Returns a function for creating arrays containing pseudorandom numbers drawn from a triangular distribution.
*
* @name factory
* @type {Function}
* @param {number} [a] - minimum support
* @param {number} [b] - maximum support
* @param {number} [c] - mode
* @param {Options} [options] - function options
* @param {PRNG} [options.prng] - pseudorandom number generator which generates uniformly distributed pseudorandom numbers
* @param {PRNGSeedMT19937} [options.seed] - pseudorandom number generator seed
* @param {PRNGStateMT19937} [options.state] - pseudorandom number generator state
* @param {boolean} [options.copy=true] - boolean indicating whether to copy a provided pseudorandom number generator state
* @param {string} [options.dtype="float64"] - default data type
* @throws {TypeError} `a` must be a number
* @throws {TypeError} `b` must be a number
* @throws {TypeError} `c` must be a number
* @throws {TypeError} options argument must be an object
* @throws {TypeError} must provide valid options
* @throws {Error} must provide a valid state
* @returns {Function} function for creating arrays
*
* @example
* var triangular = factory( 2.0, 5.0, 3.0 );
* // returns <Function>
*
* var arr = triangular( 10 );
* // returns <Float64Array>
*
* @example
* var triangular = factory( 2.0, 5.0, 3.0 );
* // returns <Function>
*
* var arr = triangular( 10, {
* 'dtype': 'generic'
