vlt.string.trimws

  TRIMWS - Trim leading whitespace from a string

    NEWSTR = vlt.string.trimws(STR)

    Trims leading spaces from a string.

    There is probably no reason for this function to exist, as the Matlab function
    STRTRIM seems to perform its function.  This function is provided for backward
    compatibility.  I recommend simply using STRTRIM rather than this function, as it
    will probably be removed in a future release.

    The only difference between STRTRIM and vlt.string.trimws is that vlt.string.trimws only operates on
    leading spaces, whereas STRTRIM removes trailing whitespace and also operates on
    any whitespace character as defined by the function ISSPACE.

    Example:
        m = vlt.string.trimws('   this string has leading whitespace')
