Wrapping numbers to an interval is not difficult and can be done with 1 line of code depending on the interval type. This function adds flexibility to this process by letting the user specify the interval type (open|closed) and by supporting the use of +/-inf in the interval.

xwrap = wrapToInterval(x, [a,b])
wraps values in x to the interval [a,b] resulting in [a <= xwrap < b].

wrapToInterval(x, [a,b], intervalType)
specifies interval type:
------ 'openright' -- results in [a <= xwrap < b]
------ 'openleft' -- results in [a < xwrap <= b]
------ 'closed' -- results in [a <= xwrap <= b]

wrapToInterval(__, plotflag)
produces a scatter plot comparison between x and xwrap.
