[FEATURE] Add if cascade without braces

[Mathias Fernandes Duarte Coelho]

Is your feature request related to a problem? Please describe.
Extension of #27, the goal is implement if cascade statement when the command use no braces, as follows:

Should be allowed

Sim-C:

if (expression)
    if(expression)
        cmd
     else
         cmd
else
    cmd 

Plus, you should ensure that when if (expresion) is called without braces and followed of else, only and necessary one instruction is between both.

Should NOT be allowed

if (expression)
    if(expression)
        cmd
        cmd 
     else
         cmd
else
    cmd 

if (expression)
    if(expression)
        cmd
     else
         // missing command here
else
    cmd

Hi there! @Math-O5
Can I work on this?
I have understood the issue, but I am still uncertain how to go about doing this, so I might need some help.

Sure assigning this to you @Chasmiccoder.

Hi guys. @Math-O5 @frankhart2018
I went through the tokens that correspond to this part of the simc code:

The tokens look like this:

So, to implement the if cascade feature, can I do this:
if tokens[i] corresponds to 'if' statement,
----count the number of newlines.
----if the number of newlines exceeds 2, then the programmer has implemented more than 1 statement in the if block,
--------print error message
----else
--------return the corresponding opcode

Please tell me if this is the right approach. I am having difficulty in finding out how many statements follow the if condition.
Thanks!

Hi @Math-O5. I got on a call with @frankhart2018
I think we need to solve #24
before we solve this issue.
If not, please tell me how to go about doing it.
Thanks

@Chasmiccoder You are right, I will work on #24 first, then
