calculateCrapScore

protected BigDecimal calculateCrapScore(BigDecimal complexity, BigDecimal coverage)
Calculate the CRAP metric score
Parameters:
complexity - - the cyclomatic complexity of a method
coverage - - the code coverage (by line) of a method
Returns:
the CRAP Metric score Given a Java method m, C.R.A.P. for m is calculated as follows: C.R.A.P.(m) = comp(m)^2 * (1 ? cov(m)/100)^3 + comp(m) See http://www.artima.com/weblogs/viewpost.jsp?thread=210575
