Functions
uint32_t	PSQt::fRGBA (const float R, const float G, const float B)
	Returns uint32_t color code for R, G, and B parameters. R - red [0,1] G - green [0,1] B - blue [0,1].
uint32_t	PSQt::HSV2RGBA (const float H, const float S, const float V)
	Returns uint32_t color code for H, S, and V parameters. H - hue [0,360) S - black/white satturation [0,1] V - value of color [0,1] ??? http://www.rapidtables.com/convert/color/hsv-to-rgb.htm http://en.wikipedia.org/wiki/HSL_and_HSV http://stackoverflow.com/questions/3018313/algorithm-to-convert-rgb-to-hsv-and-hsv-to-rgb-in-range-0-255-for-both.
uint32_t *	PSQt::ColorTable (const unsigned &NColors=0, const float &H1=0, const float &H2=0)
	Returns uint32_t* color table for requested parameters. NColors - number of colors H1, H2=[-360,360] - extended to negative hue range.
ndarray< uint32_t, 2 >	PSQt::getColorBarImage (const unsigned &rows=20, const unsigned &cols=1024, const float &hue1=-120, const float &hue2=60)
