v1.0.1

Major changes to mask.bubbles_mask_nonzero():

• Now supports non-integer products of sigma and max_sigma_from_nonzero. The previous version assumed that sigma * max_sigma_from_nonzero would always produce an integer.
• Bubble locations are now sampled from pixels identified via binary dilation, with random noise between -0.5 and 0.5 around the centre of the pixel.
• max_sigma_from_nonzero can now be an array of values, of the same length as sigma, for bubble-specific constraints.
• max_sigma_from_nonzero can be 0 or np.inf.

Minor changes:

• mask.bubbles_mask_nonzero() now passes **kwargs to mask.bubbles_mask() and build.build_mask()
• mask.bubbles_mask() now passes **kwargs to build.build_mask()
• build.build_mask() now has defaults of scale=Trueand sum_merge=False. These defaults were originally set in mask.bubbles_mask() and mask.bubbles_mask_nonzero().
• Added timing demo to examples.py, comparing bubblemask's density method to a convolution method.
• Improved all documentation, including using numpy style
• Arguments scale and sum_merge, which should now be passed as **kwargs, have been removed from documentation for mask.bubbles_mask_nonzero().
