The Number of Reads metric is used to get information about which variables are read.
Each read of a variable in an implementation is considered, but if the same variable is read twice in an implementation, it is only counted once.
Example
Number Of Read calculation example:
METH(iMyVariable);
// Some other implementation
METH(iMyVariable);
Number Of Reads Result (for variable iMyVariable)
Number Of Reads = 1
