Add more axis initialization templates

[kMutagene]

There are the following types of linear axes in plotly:

• Auto(determines the best fit from below)
• Linear
• Log
• Date
• Category
• MultiCategory

A few init functions specifically setting mandatory properties for these axis types (e.g. category order for categorical axes) would be very beneficial.

So the functions would look like this:

static member initCategorical
	(
		CategoryOrder: StyleParam.CategoryOrder,
		// all other optional properties of linear axes
	) : Axis.LinearAxis = ...
