v5.2.0

TensorOperations v5.2.0

Diff since v5.1.4

v5.2.0 attempts to improve the overall user experience by including some precompilation for the main methods of this package. For now, this is limited to Array{Float64} or Array{ComplexF64} to not overburden the precompilation time, and we'll be monitoring the implications and adjust accordingly if necessary.

• Add precompile statements (#203) (@lkdvos)
• Add aliasing warning to docs (#204) (@lkdvos)
• optimaltree hangs on edge case with all costs equal to 1 (#207) (@lkdvos)

Closed issues:

• Incorrect result when using input tensor to store result of contraction involving sum (#192)
