Check if value is lesser than an array of values

Simple but useful math function: check if a value is < than a bunch of values.


/** Check whether a value is tightly lesser than some values.

 @param val Float value to test.
 @param arr Array of all numbers to compare with.
 @return Returns true if given number is tightly lesser than all other values, false otherwise.
 @see isValue:greaterThanValues:
 @see isValue:greaterThanOrEqualToValues:
 @see isValue:lesserThanOrEqualToValues:
