mir-algorithm v0.7.0: new interpolation, optmath, bugfixes

[Nathan S.]

About Mir Algorithm
--------------------
>Mir Algorithm[1] is Dlang core library for math, finance and a 
>home for Dlang multidimensional array package - ndslice.

New Modules since v0.6.21
--------------------
- Reworked interpolation API, now found in mir.interpolate, 
mir.interpolate.linear, mir.interpolate.pchip.
- New module mir.interpolate.spline for cubic interpolation. 
Warning: multivariate cubic spline with derivatives is still 
experimental.
- New module mir.interpolate.constant for constant interpolation. 
Warning: multivariate constant interpolant is still experimental.


API Changes since v0.6.21
--------------------
- Added in mir.math.common function attributes @optmath and 
@fmamath. They only have effect when compiling with LDC but can 
be used with all compilers. (This now also applies to @fastmath.) 
@optmath is similar to @fastmath but does not allow 
unsafe-fp-math. Does not force LDC to replace division with 
multiplication by reciprocal.
- New mir.utility.extMul extended unsigned multiplication that 
makes available the high bits of the result
- New mir.functional.aliasCall
- New mir.ndslice.algorithm.maxLength returns max length across 
all dimensions.
- New mir.ndslice.slice.IteratorOf!(T : Slice) extracts iterator 
type from a Slice
- New mir.ndslice.slice.ndassign assignment utility template that 
works both with scalars and with ndslices.
- In mir.ndslice.slice.Slice: iterator is now inout; opUnary now 
works with - and +; opIndexAssign now returns ref this instead of 
void.
- mir.ndslice.field.MagicField supports length and shape.


Removed Modules
--------------------
- mir.interpolation, mir.interpolation.linear, mir.interpolation. 
Migrate to replacements (mir.interpolate.*).


Other Changes since v0.6.21
--------------------
- Uses of @fastmath in the Mir codebase have been replaced by 
@optmath, excepting mir.math.sum Summation.fast.
- In mir.ndslice.topology under-the-hood improvements in slide, 
diff, pairwise
- In mir.ndslice.slice.Slice opBinary and opBinaryRight now 
internally use mir.ndslice.topology.vmap instead of 
mir.ndslice.topology.indexed.


Fixed since v0.6.21
--------------------
- Fix in mir.ndslice.topology.map for compilation failing in 
cases where chained map calls couldn't be coalesced due to 
capturing multiple contexts (seemingly a compiler bug in some 
cases)
- Made mir.ndslice.topology.flattened backwards compatible with 
LDC 1.2.0 for those who haven't upgraded
- Added workaround in mir.ndslice.algorithm.reduce for DMD 
inlining bug for non-Windows x86-64 (LDC unaffected)
- mir.primitives.shape now takes its argument by reference
