protected String email;

public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
/**
* Returns the name.
* @return String
*/
public String getName() {
return name;
}

/**
* Set the name.
* @param name The name to set
*/
public void setName(String name) {
this.name = name;
}

/**
* Returns the address.
* @return String
*/
public String getAddress() {
return address;
}

/**
* Set the guide_type.
* @param address The address to set
*/
public void setAddress(String address) {
this.address = address;
}

/**
* Returns the email.
* @return String
*/
public String getEmail() {
return email;
}

/**

public void setEmail(String email) {
