Generate code from a mermaid markdown file

Example

From a mermaid code like this:

    A "1" o-- "1..N" B
    B "N" *--* "M" C
    A "0..N" --* "1" C

    class A {
        +int vertejums
        +string atsauksme
    }
    class B {
        +string nosaukums
        +string atrasanas vieta
        +string apraksts
    }
    class C {
        +string tips
    }

which, with the help of Mermaid JS generates a diagram like this

and with the help of this utility code generates this:

from django.db import models

class C(models.Model):
    tips = models.CharField(max_length=100)

class A(models.Model):
    C_fk = models.ForeignKey('C')
    vertejums = models.IntegerField()
    atsauksme = models.CharField(max_length=100)

class B(models.Model):
    A_fk = models.ForeignKey('A')
    C_fk = models.ManyToManyField('C')
    nosaukums = models.CharField(max_length=100)
    atrasanas = models.CharField(max_length=100)
    apraksts = models.CharField(max_length=100)
