/**
* Computes the incomplete gamma function. The upper tail is calculated via the modified Lentz's method for computing continued fractions, the lower tail using a power expansion.
*
* @private
* @param {NonNegativeNumber} x - function parameter
* @param {PositiveNumber} a - function parameter
* @param {boolean} regularized - boolean indicating if the function should evaluate the regularized or non-regularized incomplete gamma functions
* @param {boolean} upper - boolean indicating if the function should return the upper tail of the incomplete gamma function
* @returns {number} function value
*
* @example
* var v = gammainc( 6.0, 2.0, true, false );
* // returns ~0.9826
*
* @example
* var v = gammainc( 1.0, 2.0, true, true );
* // returns ~0.7358
*
* @example
* var v = gammainc( 7.0, 5.0, true, false );
* // returns ~0.8270
*
* @example
* var v = gammainc( 7.0, 5.0, false, false );
* // returns ~19.8482
*
* @example
* var v = gammainc( NaN, 3.0, true, false );
* // returns NaN
*
* @example
* var v = gammainc( 1.0, NaN, true, false );
* // returns NaN
