    )

Top level Kernel function. Consists of INIT_LOOP and main sample loop: SAMPLES_LOOP

Generates sample from target distribution function.

Uses multiple Markov Chains to allow drawing samples from multi mode target distribution functions.

Proposal is generated ussing Normal Distribution

.

Parameters:

DT	Data type used in whole function (double by default)
NCHAINS	Number of chains
NSAMPLES_MAX	Maximum Number of chains for synthesis purpose
temp_inv	Array of Inverted temperatures of the chain that density is generate for (1/Temp)
sigma	Array of sigmas for Proposal generation for each chain
nSamples	Number of samples to generate
x	Sample output
