coord: make template parameters more flexible
...
The coordinate system was unable to support types that prohibited
redim or retype operations. Additionally, the `tags' type used for
providing named data parameters was unwiedly.
We remove much of the dependance on template template parameters in the
defined operations and instead define these in terms of a template
specialisation of is_coord.
The tag types were replaced with direct specialisation of the `store'
struct by the primary type, and passing this type through use of the
CRTP.

build: don't use './' as an include prefix
...
GCC produces ODR error when including paths of the form './foo' and
'foo' in the same binary. Rather than managing duplication we just
universally pick the absolute form over the relative form.

coord: don't use kahan summation for sum(coord)
...
Our kahan summation algorithm has issues with infinities so we just
avoid using it in coordinates where speed and simplicity are more
important.

maths: use mult rather than negation in constexpr

util::digits was triggering signed overflow warnings under gcc. By using
negative multiplication rather than explicit negation we get the same
behaviour, sans warning.
