Mean shift for finding modes

The submission finds modes in data. Data is generated from a mixture of gaussian with added outliers

Run plotModes() to see result.
Note: 40% generated data is added outlier.

Correction:
In findModes.m, go to kernelized_weights() function and replace:
euclidean_dist = sum(offset.*offset,2) .* inv_bandwidth_sq;

with:
euclidean_dist = sum(offset.*offset,2);
