Parity with https://github.com/jheinen/GR.jl/commit/944d4caaa2

From #45: > I currently observe a slight performance loss of 30-40% when switching from GR to GRUtils. I would like to investigate this in more detail. I have made...

Differences with GR polar plots

3

Take this code: ```julia angles = LinRange(0, 30, 100) radii = LinRange(-2, 4, 100) polar(angles, radii) ``` This is the output of GR:  But GRUtils makes this:  There...

Specialized type for Boolean sparse arrays

Recurrence matrices are wrappers of `SparseMatrixCSC{Bool,Int}`, which are useful to make some operations. However it is inefficient to create them (cf. #76), and also take more memory than what is...

Improve performance with `fixedrate=true`

In the calculation of recurrence matrices with fixed recurrence rate there is the issue commented in #46 (indirectly calling `distancematrix`, which is expensive): https://github.com/JuliaDynamics/RecurrenceAnalysis.jl/blob/2961a32b29e41ea1e3dc3d63f67e29d74948e5ab/src/matrices.jl#L220-L222 A function that gives the same...
