Tuple<T> and a couple of functions on it are now working according to
the target spec. As desired, no instantiations of a template type
are made until some function that takes an instantiation is called.
This adds the target initial definition of a homogeneous Tuple<T>
type, and just enough processing that the type can be defined and
non-template methods that deal with the generic base type Tuple can
be called. Still has no actual template instantiation.
Also adds a `mean()` operation so there will be at least one operation
that takes only a rest parameter, to exercise the ban on splitting
such a parameter between the stored value and new arguments.
Adds various tests of chains.
Resolves#32.
Relational functions are added using templates, and existing generic functions are made more strict with them. Also a new built-in typeOf function is added, that automatically updates itself.
Resolves#34.

This should eventually be moved into typed-function itself, but for
now it can be implemented on top of the existing typed-function.
Uses subtypes to define (and error-check) gcd and lcm, which are only
defined for integer arguments.
Resolves#36.
Merging of Pocomath modules is eased by allowing one PocomathInstance to
be merged into another. That allows types, for example, to be exported
as a PocomathInstance (so there is no need for a special identifier
convention for types; they can be directly added with an installType
method). Also, larger modules can just be exported as an instance, since
there is more flexibility and more checking in merging PocomathInstances
than raw modules.
This allows types to be collected; prior to this commit they
were conflicting from different modules.
Uses this fix to extend sqrt to bigint, with the convention
that it is undefined for non-perfect squares when 'predictable'
is false and is the "best" approximation to the square root when
'predictable' is true. Furthermore, for negative bigints, you might
get a Gaussian integer when predictable is false; or you will just get
your argument back when 'predictable' is true because what other
bigint could you give back for a negative bigint?
Also had to modify tests on the sign in sqrt(Complex) and add functions
'zero' and 'one' to get types to match, as expected in #27.
Adds numerous tests.
Resolves#26.
Resolves#27.
Also implements a config object that upon change, lazily invalidates
all operations that access it.
Also allows references to signatures with nonexistent types (which
typed-function does not); they come back as undefined.
Uses these features to implement sqrt for number and complex.
Resolves#7.
Allows dependencies to be economically expressed and used.
For example, see the new definition of subtract.

Also starts each PocomathInstance with no types at all, and uses the new
situation to eliminate the need for a Complex "base case".
