Binds $Model to $ModelAdmin without having to specify each binding manually. The ModelAdmins must have the same name as the model (as well as same case) with Admin appended.

Example: from django.db import models

class SomeModel(models.Model):
    name = models.CharField(max_length=255)

class AnotherModel(models.Model):
    name = models.CharField(max_length=255)

# bind administration
bind_administration('myproject.myapp.models', 'myproject.myapp.admin')
