Support more then 32 qubits in simulation.

Allow gates to be specified inside a .qc file so that circuits with custom gates can be easily loaded.

You need cairo 1.10.2 or higher which isn't available on 10.04 LTS, so 12.04 is needed.

You need to install a few more dependencies:

apt-get install libpoppler-glib-dev
apt-get install libgtkmm-2.4-dev libglademm-2.4-dev

I am not sure if glademm is actually required.

It would be nice to update the README with these notes if you have a chance.

I am trying to build this project QCViewer，I just installed the all Build dependence for this project， on Ubuntu 18.04 LTS， and tried to run ./build. But CMake just does not want to find it and i dont know why. What am i missing? Do i need to set an environment variable or something?
`CMake Error at QCViewer/CMakeLists.txt:63 (FIND_PACKAGE):

-Add circuit descriptions/authors to the .qc format
-better input output specification

Change the .qc file format into something like this (while keeping support for the old format):

VERSION "1.0"

IMPORT carrySelect FROM "adder.qc"

BEGIN test (a b c)
  BEGIN HEADER
    Author = "blah"
    Description = "Blah"
    foo = "bar"
  END HEADER
  BEGIN BITINFO
    INLABELS a : ain , b : stuff
    OUTLABELS a : aout , c : garbage
    INIT a : |0>+|1> , c b : |00> + |11>
  END BITINFO
  BEGIN GATES
    H a
    toff b c
    :NEWBIT n
    toff b n
    toff b n
    :FREE n
  END GATES
END test

Add better support for subcircuts. Including the ability to expand and collapse them in the viewer mode.

Add latex support for things such as line names and labels.

-Specific gate counts and depths

Display rotation gates as a fraction of pi rather then a decimal number multiplied by pi. This will require changes to .qc to specify the fraction as well as changes to the drawing system to display it as a fraction.

Need to do this since latex and pango use different syntax for superscript. Also would be nice for user defined gate names/symbols.

Currently the lack of this causes a bug when viewing gates which have superscript in latex mode.

-Should not be done as global data.

Have a file per gate as well as folder per gate library. This will allow the user to easily import new gates from others.

Add measurement. Requires changes to sim for density matrices as well as changes to .qc to specify measurement gates.

Draw a dim dotted box to indicate where a gate would go under drag and drop. This will 1) Aid the user 2) Aid debugging.
