Parallelized the CALIC implementation

[siddharths2710]

Filled various lines of code with #pragmas while taking care of race conditions and thread-safety.

Example:

#pragma omp parallel for private(temp) reduction(+:sum)
for (int i = 0; i < ns; i++) {
temp = pow(15.0, 0.4 * (double)(-i-1)); //prevent false sharing and double indirect addressing overhead
freqPercentage[i] = temp;
sum += temp;
}

Here the variable temp is private to every thread created to run a portion of the for loop, and is computed in parallel with other iterations. To prevent racing, all the temp values generated by the threads are added one by one to the variable sum.
