fix(frontends/lean): alias generation for composite names was not working

This is an issue for declarations that generate composite names such as
the inductive datatype packacke.

fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286
...
The problem was that heq type is
Pi {A : Type} (a : A) {B : Type} (b : B), Prop
The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.
The fix is to remove this assumption.

We can declare variables anywhere. So, we must also be able do declare

this feature
```
-- We want A and B to be in the same universe
universe variable l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```
The following doesn't work because A and B are in different universes
```
variable A : Type
variable B : Type
definition tst := A = B
```
The following works, but tst is not universe polymorphic, since l is
one *fixed* global universe
```
universe l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B

This is not exclusive to equality.
It applies to any inductive datatype in Prop, containing only one
constructor with zero "arguments" (we say they are nullary).
BTW, the restriction to only one constructor is not needed, but it is
does not buy much to support multiple nullary constructors since Prop is
proof irrelevant.

methods
It is not safe to use seekg for textual files. Here is a fragment from a
C++ manual:
seekg() and seekp()
This pair of functions serve respectively to change the position of stream pointers get and put. Both functions are overloaded with two different prototypes:
seekg ( pos_type position );
seekp ( pos_type position );
Using this prototype the stream pointer is changed to an absolute position from the beginning of the file. The type required is the same as that returned by functions tellg and tellp.
seekg ( off_type offset, seekdir direction );
seekp ( off_type offset, seekdir direction );
Using this prototype, an offset from a concrete point determined by
parameter direction can be specified. It can be:
ios::beg offset specified from the beginning of the stream
ios::cur offset specified from the current position of the stream pointer
ios::end offset specified from the end of the stream
The values of both stream pointers get and put are counted in different
ways for text files than for binary files, since in text mode files some
modifications to the appearance of some special characters can
occur. For that reason it is advisable to use only the first prototype
of seekg and seekp with files opened in text mode and always use
non-modified values returned by tellg or tellp. With binary files, you
can freely use all the implementations for these functions. They should
not have any unexpected behavior.
