verLessThanFS compares version of MATLAB to specified version number

`result=verLessThanFS(vernumber)`

example

function verLessThanFS is much faster than verLessThan because it just checks the version of MATLAB and calls directly the relevant built in functions. The number containing the MATLAB version is cached for better performance. In order words, the first time verLessThanFS is called the vector with two numbers associated to the MATLAB version is stored in persistent variable named cachedMatlabVerFS.
